TECHNICAL FIELD

The disclosure relates to an electronic device including a button for auser information input and a method for an operation in the electronicdevice.

BACKGROUND

Recently, electronic devices have evolved into various types for userconvenience.

Electronic devices have evolved into various types, such as an inputmeans for an input interface used to manipulate an external electronicdevice and to input user information by the external electronic device.Such input means include an electronic device having a pen function (forexample, a stylus or an electronic pen), and user information may beinput to an external electronic device including a touchscreen throughthe touchscreen of the external electronic device.

Electronic devices having the pen function commonly adopt anelectromagnetic resonance (EMR) type among input types, and a Bluetoothfunction-based input type has recently been developed.

An electronic device having a pen function tends to be configured suchthat the same can be mounted on an external device in view of the user'sconvenience and portability of the device, or such that the device sizeis made smaller, and may have a button as an input interface for a userinput.

In order to apply various functions or various input types, however, onesingle button needs to be used to perform one function, or other buttonscorresponding to various input types need to be provided additionally.

However, adding and configuring buttons makes the structure of theelectronic device complicated, and if the electronic device isaccordingly configured to be mounted on an external device, the externaldevice needs to have a large mounting space and becomes complicated.

In addition, if a Bluetooth function is applied as another input type tothe electronic device, the Bluetooth function operates every time theuser conducts a button input and quickly reduces the current in thesmall-capacity battery. This may cause inconvenience in using theelectronic device.

SUMMARY

According to various embodiments, an electronic device including abutton and a method is provided, wherein an EMR input type or aBluetooth low energy (hereinafter, referred to as BLE) input type isselectively determined according to whether or not an approach signal isidentified, thereby reducing battery current consumption.

According to various example embodiments, an electronic device mayinclude: an elongated housing including a first end and a second end; adielectric tip disposed at the first end; a button arranged on an outersurface of the housing; a first circuit connected to the dielectric tipand configured to receive a first electromagnetic signal from atouchscreen display of an external device and to transmit a secondelectromagnetic signal to the display of the external device; a secondcircuit configured to wirelessly receive and transmit a third signal;and a control circuit operatively connected to the first circuit and thesecond circuit. The control circuit may be configured to: detectpressing and/or touching of the button while the first electromagneticsignal is received through the first circuit and transmit the secondelectromagnetic signal while preventing the second circuit fromtransmitting the third signal; and detect pressing or touching of thebutton without receiving the first signal through the first circuit andtransmit the third signal while the second signal is not transmitted.

According to various example embodiments, an electronic device mayinclude: an elongated housing including a first end and a second end; adielectric tip disposed at the first end; a button arranged on an outersurface of the housing; a first communication unit comprising firstcommunication circuitry connected to the dielectric tip and configuredto receive a first electromagnetic signal from a touchscreen display ofan external device and to transmit a second electromagnetic signal tothe display of the external device; a second communication unitcomprising second communication circuitry configured to wirelesslyreceive and transmit a third signal; a processor operatively connectedto the first communication unit and the second communication unit; and amemory electrically connected to the processor. The memory may includeinstructions that, when executed, cause the processor to control theelectronic device to: transmit the second signal to the external devicewhile preventing a third signal from being transmitted through thesecond communication unit in response to pressing and/or touching of thebutton, while the first signal is received through the firstcommunication unit; and transmit the third signal to the externalelectronic device through the second communication unit in response topressing and/or touching of the button, while the first signal is notreceived through the first communication unit.

According to various example embodiments, a method for an operation inan electronic device including a button for a user information input mayinclude: receiving a first electromagnetic signal from a touchscreendisplay of an external device; detecting pressing and/or touching of thebutton; transmitting a second electromagnetic signal to the display ofthe external device, while preventing a third signal from beingtransmitted through a first communication unit, in response to pressingor touching of the button while the first signal is received; andtransmitting the third signal to the external device through a secondcommunication unit in response to pressing and/or touching of the buttonwithout receiving the first signal.

An electronic device and a method for an operation in the electronicdevice according to various example embodiments may have at least thefollowing advantages: the electronic device detects pressing and/ortouching of a button, selectively determines an EMR input type or a BLEinput type according to whether or not an approach signal is identified,and transmits a signal that follows the determined input type to anexternal electronic device. Accordingly, there is no need toadditionally configure a separate button, and the BLE operationresulting from button pressing is minimized and/or reduced, therebyreducing battery current consumption; and the actual time of use of theBluetooth module is accordingly reduced.

In this case, the button input signal(SW1 signal) may not be transferred to the control circuit 640 throughthe fourth path 904. According to various embodiments, the capacitanceC2 647 and the resistor R3 649 included in the control circuit 640 mayperform operations of low-pass filters so as to prevent erroneousoperations of the second circuit 620 due to the operating voltage of thefirst electronic device 201, which is transferred from Vres when thefirst switch SW1 615 is turned off. The second circuit 620 may operatewhen the input is zero as a result of an active-low operation. That is,when the input value of the second control signal 913 is zero, thesecond circuit 620 may recognize that the button (for example, thebutton 411 of FIG. 4) of the first electronic device 201 is pressed.

Although it has been assumed in the above description of variousembodiments with reference to FIG. 9A that the second circuit 620 isactivated when receiving a low signal according to an active-lowoperation, the second circuit 620 may be activated when receiving a highsignal according to an active-high operation in another embodiment.

According to various embodiments, when the first electronic device 201is positioned in-range on the touchscreen 301 of the second electronicdevice 101, and when the same senses pressing or touching of the buttonarranged on the surface of the housing, the button switch SW1 615 of thefirst circuit 610 may be turned on, and the first circuit 610 maytransfer a button input signal B to the control circuit 640 through thethird path 903. In this case, the resonance circuit of the first circuit610 may generate an electromagnetic field signal (for example, a secondelectromagnetic field signal), the frequency of which is changed.According to various embodiments, if the control circuit 640 receives abutton input signal B through the third path 903, and if the samereceives an approach signal A from the third circuit 630, the same maytransfer a first control signal 911 corresponding to the approach signalA and a second control signal 913 corresponding to the button inputsignal B to the second circuit 620 through the sixth path 906 such thatthe second circuit 620 does not transmit a third signal.

According to various embodiments, the control circuit 640 may transferoperation result values, which are obtained by operations based on theapproach signal and the button input signal, to the second circuit 620such that the second circuit 620 does not transmit a third signal. Theoperation result values may include an EMR button value and/or a BLEbutton value for determining the button input type. Since the secondcircuit 620 operates according to active-low, the second circuit 620 maytransmit a third signal to the second electronic device when the BLEbutton value (operation result value) is zero.

Although it has been assumed in the above description of variousembodiments with reference to FIG. 9A that the second circuit 620 isactivated when the input is zero according to an active-low operation,the second circuit 620 may be activated when the input is one accordingto an active-high operation in another embodiment.

After recognizing the value of the approachsignal A as 1 and recognizing the value of the button input signal B as1, the control circuit 640 may determine, through operations, that thevalue of the EMR button EMR BUTTON is 0, and the value of the invertedBLE button BLE BUTTON is 0. Accordingly, the second circuit 620 mayrecognize that the value of the EMR button EMR BUTTON is 0, and thevalue of the BLE button is 1, as illustrated in FIG. 9A.

When the first electronic device 201 is positioned in-range on thetouchscreen 301 of the second electronic device 101, and when pressingor touching of the button arranged on the surface of the housing issensed, the control circuit 640 may recognize that the value of theapproach signal A is 1 as a result of receiving the approach signal Aand, as in Table 1 below, and may recognize that the value of the buttoninput signal B is 0 as the button switch SW1 615 is turned on.

Accordingly, the third circuit 630 connected to the firstcircuit 610 may not receive an approach signal A corresponding to theelectromagnetic field signal, and the approach signal A may not betransferred through the fifth path 905. When the button switch SW1 615is turned off, the first circuit 610 and the control circuit 640 are inshort-circuited states, and no voltage is applied to the third path 903.In this case, the button input signal B may not be transferred to thecontrol circuit 640.

As a result, a button inputsignal B may be transferred to the control circuit 640 through the thirdpath 903.

According to various embodiments, when the first electronic device 201is positioned out-of-range on the touchscreen 301 of the secondelectronic device 101, the fourth switch M4 631 and the third switch M3645 may be turned off, as in Table 2 below, and the first switch M1 641and the second switch M2 643 of the control circuit 640 may be turnedoff because the approach signal A is not received by the control circuit640.
